Description
The NP1500 front-end power supplies are specifically
designed to operate as an integral part of a complete
distributed power system. A full complement of alarm
and shutdown features have been incorporated into
the power supply to protect the system in the event of a
fault condition. The flexible feature set makes this frontend power supply an excellent choice for applications
requiring modular ac-to-dc bulk intermediate voltages,
such as distributed power. Features reflect an emphasis on worldwide acceptance of this power system.

20 MHz bandwidth under any load

Measured between the 10% and 90%
points of the waveform. At any normal
load condition. Voltage slope will
always be greater than or equal to
zero.
The overshoot is with respect to the
initial set point.
At 52 Vdc, maximum delay to
shutdown initialization is 64ms.
With rectifier output margined to 58V,
no step load change will cause highvoltage shutdown. If output voltage is
operating within specified range for
greater than 50ms, unit will shutdown.
Duration of overvoltage condition
above 60V limited to maximum
100ms.
25% step at 25% to 75% static.
10% step at 0% to 25% static.
No HV shutdown for any transient
load change. Load transient current
delta to be within 250 ± 25 µs. The
induced output voltage transient
settles to within 1% of the final voltage
in less than 10 ms. All data given are
for resistive loads.
12,500 µF Typ.
ORing diode.
Measured from application of valid ac
voltage for default unit set point.
Note: Rectifiers may be purchased with the output set to any voltage in the range 42 ≤ VO ≤ 58V with the
output performance as noted above. Users may also margin the output voltage to any voltage in the
range 42 ≤ VO ≤ 58V with an optional Network Protocol Card. When the rectifier is programmed to
an output voltage within the range of 52V ≤ Vo ≤ 58V, the rectifier output current is adjusted so that
a constant power is delivered. However, when the rectifier is programmed to an output voltage
within the range of 42V ≤ Vo < 52, the output current is maintained at that for 52V, therefore, the
rectifier produces less power. For example, if the NP1500 is programmed to 48V, the resultant
output power would be 1440W (48V x 30A---30A is the current limit set point for the NP1500).

Figure 1. NP1500 Factory-Set Output Voltage and Current
Factory Default Performance at 52V:
If the unit initially powers up at low line (85-135Vac), the unit becomes a 1200W unit. If the line voltage is
then increased to high line (150 to 264Vac), it will remain a 1200W unit.
If the unit initially powers up at high line (150-264Vac), the unit becomes a 1500W unit. If the line voltage is
then lowered to low line (85-135Vac), the unit shuts off.
The rectifier shuts off in the dead-band zone between 132Vac and 150Vac.
The power unit will operate in the constant voltage mode until the load current exceeds IL, which is 105%
of IO. The power supply during startup will allow 36A at high line operation, or 30A at low line operation, for
200 ms to start dc/dc converter modules. After the initial startup, the current limit reduces to 30A at high
line operation, or 24A at low line operation.

Physical Descriptions
Definition of Terms
Power-Factor Correction
All NP-Series power supplies comply with the
specifications set forth in EN61000-3-2.
Input Overcurrent Protection
An internal fuse is provided in each unit for input
protection in compliance with safety agency
requirements.
Overcurrent Protection
In the event of an overload condition, the power
supply limits the output current. See Figure 1 for
details.
Overvoltage Protection
The power unit turns itself off before the output
voltage reaches a specified threshold.
Overtemperature Protection
In the event of an overtemperature condition, the
power unit protects itself by shutting off. Restart
can be accomplished with a toggle of remote on/
standby.
ORing Diode
A diode at the output of the power unit protects the
dc bus in the event of a power supply failure or hot
plugging of the power unit.
NP1500 Constant Current Front-End Power Supply
85 Vac to 264 Vac Input, 42 Vdc to 58 Vdc Output
Reset
Toggle the Remote On/Standby to accomplish
reset.
Redundant Bias Supply (EX_BIAS_12—15 V)
This protected feed from the internal bias supply
may be used to externally power the alarm and
control logic.
AC Line Discrimination
The unit senses the input range at power-up and
shuts the unit down if the input drops below that
line range for a specified period of time.
Variable Speed Fan
Fan spins at lower rpm at room ambients. When
ambient temperature exceeds approximately 27°C,
the fan speed is linearly increased until approximately 35°C when the fan spins at full speed.
Front Panel LEDs
AC OK (green):The unit has input ac in the correct
range.
DC OK (green):The unit is powered up and the
output is in regulation.
Fault (red):
The unit has detected an internal
fault.
Status Signals
The following are the optically isolated open-collector signals (minimum 1 mA sinking capability):
Remote On/Standby
An opto-isolated input signal. An external 1 mA, 5
V source activates a standby condition in the
power module.
Fault:
Voltage Margining
Output voltage may be adjusted between 42V and
58V. Call factory for details.
Power Fail Warning: The output of the power unit
will fail in at least 5 ms.
Power Fail Warning (PFW)
Communicates incipient loss of output power.
Opto-isolated and pulled to ground to activate.
Front-End Power Supply Interfaces
Alarm Return (AR)
Common return for all opto-isolated signals including OTW, remote on/standby, and PFW.
The unit has detected an internal fault.
Overtemperature Warning (OTW): The unit is
overheating; shutdown is imminent
(8 second warning).
Input Voltages
The product can be used with any standard global
line voltage; consult the factory for any particular
regional application concerns.
Current Share (I_SHARE)
A single-wire interface between each of the power
units forces them to share the load current.
Input Connector
The ac input connection is through an IEC60320
C-13 connector rated at 10 A/250 Vac in Europe/
Asia, and 15 A/120 Vac in North America.
Remote Sense (R_SENSE)
These signals permit the power units to compensate for a voltage drop across the output distribution.
Grounding
Frame ground can be connected so that the output
may have either a positive or negative ground.
